7) Workers' incentive to get high-raid jobs would be discouraged.
(b) (i) Since there are many other fruits which can substitute orange, the demand for it is elastic. In such case, the producers of orange would like to increase supply to the con- sumers. It is because an increase in the auentity: supplied will increase the total income of producers: when demand is elastic.
(ii) Since salt is necessary and indispensable to life, there is no close substitutes for it. Thus the demand for it is per fectly inelastic. In such case, producers of salt will be reluctant to incre.... ase supply to the consumers. It is because an increase in supply will result in a. decrease of the nrice of salt, and producers' total income will be lower than before. Contrarily produan.
cers would try to maintain supply unchanged or even at a lower level in order to get satisfactory or higher incomes.
